I need to get hold of some chlorine to disinfect a well. From some research
"plain" bleach seems like the obvious candidate. However, I'm struggling to
find bleach that
a) lists the active ingredient as sodium hypochlorite and
b) lists its concentration and
c) doesn't contain perfume.

Can anyone suggest an easily available (UK) product meeting all the above
criteria?

Thanks,
Piers

Tesco Thin Bleach, the cheap stuff in the white/blue stripe container.

b) lists its concentration

Tesco Thin Bleach 5% Sodium Hypochlorite (4-5% in practice).

c) doesn't contain perfume.

Alternatively any farm supplier should stock Sodium Hypochlorite 10%
(Red Label Hypochlorite) at about £10/25L

Does it have to be Sodium hypo? Just talk to your local swimming pool
chemicals supplier who will sell you pure calcium hypochlorite in powder
form.

Have you looked at swimming pool chlorine? That would seem to satisfy your
requirements, though I'm not sure if that's hypochlorite.

Sainsbury's value range bleach.



Most household bleach contains caustic soda for some reason, certainly
the thickened types. I was going to suggest Milton for purity but, as
already suggested, an agricultural supplier would be favourite for this
application.

As others have suggested, swimming pool supplies, farm/agricultural
supplies or janitorial supplies.

I keep a drum of liquid chlorine (14/15% sodium hypochlorite) for the
swimming pool, together with stabilised chlorine.

DON'T try stabilised swimming pool chlorine, it contains cyanuric acid as
the stabiliser, which basically doesn't break down, and can only be
dispersed by dilution.

Thanks to all for the replies. Sadly (!) Tesco and Sainsbury aren't
immediately available shops for me (and I would rather not give them any
business I don't have to, but that's another matter). The country store I
tried doesn't do Red Label Hypochlorite, but I've found a decent looking
online source of 15%.

I decided against using swimming pool tablets because I've read a suggestion
that they the chlorine doesn't disperse as well or as quickly - the tablets
tend to sit on the bottom. I decided against calcium hypochlorite mainly
because of hassle factor - there's less need to "dilute" or mix sodium
hypochlorite before pouring into the well, although I may do so anyway
depending on what quantity I end up calculating I need.
